Take a break from all-black suiting and mix things up with this slim fit men’s jacket, featuring a grey textured pattern that looks great with navy, grey, white or black trousers. The single breast features two buttons that have been fused with our Buttonsafe™ technology, while double vents help keep it crease-free for longer. This grey suit jacket is fully lined so it maintains its shape and keeps you warm, whether you’re headed to an important meeting or a formal family event.
